I am just sitting here thinking. If the kissing challenge would not be resolved via them kissing, who would get roped into judging? Big Mac is the obvious choice. However Cheerilee would say no to that. For best comedic effect we would need a male pony that neither one of them wants to kiss. Maybe Trixie would call upon Snips or Snails to judge which of them were the best kissers. (I don't think either of them would be able to render a good judgement as a kiss from 2 pretty mares would possibly cause them to faint.)

Although I really enjoyed and came to love the original innocent and slife of life style of MLP I wouldnt mind if they went a bit pg-13 or even r with adult jokes, sexual innuendos like this and more serious story lines. I mean at this point the majority of fans is older than 13 anyway XD
